Nope.

They don't meet the requirements of the triangle inequality.
2.1 + 4 = 6.1 < 7.9
The triangle inequality requires the sum of any two sides be greater than the third side.

What is the length of the arc shown in​ red?
professor190 [17]

Answer:

≈ 18.8 cm

Step-by-step explanation:

The arc length is calculated as

arc = circumference of circle × fraction of circle

The central angle is equal to the arc subtending it, that is 60°

  arc = 2πr × \frac{60}{360}

        = 2π × 18 × \frac{1}{6}

        = 36π × \frac{1}{6}

        = 6π ≈ 18.8 cm ( to 1 dec. place )
